SPECIFICATION forming part of LettersPatent No. 509,770, dated November 2b, 1893.
Applicata nea November 25,18%. stranamente. (mman.)
`To all whom it mag/concern: l
Be it knownthat l, CHARLES F. SUQTT, a vcitizen of the United States, residingin the city of Pittsburg, in the county ot Allegheny,
' {State-of Pennsylvania, have invented a new 'and useful Improvement in Laminated Converter-Cores, (Case No. 518,) ot which the following is a specification.
My invention relates to converters for alternating electric currents and methods for One object of my invention is'the provision of a method of stamping;r the plates whereof electric converters are composed such that from a. large sheet but allshall be consu-med in the plates as-made.
Another object of my invention vis the pro' vision of a converter composed of plate's'built with maximum stability' and with the least expense of time consumed in the adjustment of the coilsto the core. The nature of my invention is fully disclosed in the accompanying drawings, in which- 1 Figure 1 is a View of the wide plate used 'as a'bl'ank, showing in dotsA the lines along which the blank is stamped. Fig. 2 is a simi lar view of the narrow blank, and Fig. 3 shows in perspective the manner in which broad and narrow plates are laid together with relation to the coils to form my converter.
, The broad plate shown in Figui is firstl stamped progressvelyor otherwise divided along the dotted' lines shown. The strips 'one-half as wide as the middle ones. The
narrow strip shown in Fig. 2 having been ltreated in the same manner as the broad strip, -E-shaped plates 14 are produced, which when brought against the plates 13, as 'shown there shall be 'no iron wasted in stamping E' thus cnt out are similar in outline and are in Fig. 3, producea closed magnetic circuit l of two branches around the converter coils in the openings 15 and 16.
'lhe object of 'ng toothed plates of dit ferent widths is to permit of their breaking vjoints in being assembled in Ihecmnpleted core. 'lhe niode of bringing successive elements of the converter together is plainly shown in Fig. 3, where it will be seen that alternate laminae have the positions of the broad and narrow plates reversed.. -The result is that successive points of Ijunction between piates are not superimposed and the solidity of the whole structure is insured.
A further advantage from breaking uoints in successive plates'lies in the better magnetic circuit thus produced.' It the E-plates v.were all of the saine width, and all met yin a y single plano in the middle of the converter,
all the lines of force wol'lld necessarily havev to pass across the high-resistance joint be' tween the plates.4 Where thel joints are broken, however, when lines of force reach a joint in a given plate they are free to take a side course through the integral plates above and below the joint. Thus the total mag' netic resv ,tance is gr' tly decreased at the joint. c
What I claim is c 1. The method of forming plates for buildinglaminated cores which consists in dividing a rectangular .strip along a continuousl rectangularly broken line so as tot form two strips having'teetho uniform width and then dividing each toothed strip through the middle of alternate teeth, substantially as described 2. The method 'ot' forming two elementsot laminated cores which consists in dividing a broad .and a narrow rectangular strip along` continuous rectangularly broken lines, so as to form four strips having teeth of equal and unifornrwidth, dividing each strip through the middle of alternate teeth, and setting a narrow toothed plate opposite each broad one with the outer edges of their teeth juxtaposed;

D. 1892. being piled up with joints between the plates on alternately opposite sides of the CHAS F SCOTT' 5 median plane of. saidl core, substantially asl Witnesses:

In testimony whereof I have hereunto snb- HAROLD S. MACKAYE.
